Problem adding Domain Controller role to W2K3 server in an existing domain
Posted on 2007-10-12
We have a small domain consisting of a single Domain Controller which is also running Exchange 2003.
We'd like to add the Domain Controller role to another W2K3 server. However we are facing a problem.
We go through the Manage your Server option, and choose to add the Domain Controller Role. this launches an Active Directory Installation wizard that steps us through a few things.
After inputting the required data the process fails with the following error message:-
The operation failed because:
The Active Directory Installation Wizard cannot continue because the forest is not prepared for installing Windows Server 2003. Use the Adprep command-line tool to prepare both the forest and the domain. For more information about using the Adprep, see Active Directory Help.
"The version of the Active Directory schema of the source forest is not compatible with the version of Active Directory on this computer."
Both servers are at the same service pack level.
We've tried adding this role to a number of different W2K3 servers all with the same error. Is it related to Exchange 2003 being installed on the source DC?
